An update on the central nervous system manifestations of DICER1 syndrome.

Acta Neuropathol 2019 Apr 5. Epub 2019 Apr 5.

Department of Pathology, Boston Children's Hospital, Harvard Medical School, 300 Longwood Ave, Bader 104, Boston, MA, 02115, USA.

DICER1 syndrome is a rare tumor predisposition syndrome with manifestations that predominantly affect children and young adults. The syndrome is typically caused by heterozygous germline loss-of-function DICER1 alterations accompanied on the other allele by somatic missense mutations occurring at one of a few mutation hotspots within the sequence encoding the RNase IIIb domain. DICER1 encodes a member of the microRNA biogenesis machinery. Read More

Cystic lung lesions mimicking hydatidosis: hamartoma or benign metastazing leiomyoma?

Ann Thorac Surg 2019 Feb 27. Epub 2019 Feb 27.

Department of Pathology, Strasbourg University Hospital, 1 Place de l'Hopital, 67000, Strasbourg, France.

We report an unusual case of a 53-year-old woman who presented with multiple lung cystic lesions presumed to be related to pulmonary hydatidosis, treated and followed for 3 years before surgical removal was decided. Unexpectedly, pathological findings showed the presence of benign spindle cell proliferation. Immunohistochemical staining confirmed the smooth muscle nature of the spindle cells which were also positive for hormonal receptors and corresponded to multiple cystic pulmonary hamartomas.

Follicular thyroid carcinoma metastatic to skin: a small papule and a big diagnostic change.

An Bras Dermatol 2019 Jan-Feb;94(1):76-78

Department of Pathology, Laboratório Bacchi, Botucatu (SP), Brazil.

Cutaneous metastases are uncommon in daily practice, although very important, since they may be the first manifestation of an undiscovered primary neoplasm or the first indication of recurrence. Cutaneous metastases from the breast are the most frequent in women and cutaneous metastases from the lung are the most frequent in men. Thyroid carcinoma, despite representing the most frequent endocrine neoplasm, is considered a rare neoplasm, corresponding to 1% of malignant neoplasms diagnosed. Read More

First case report of malignant peritoneal mesothelioma and oral verrucous carcinoma in a patient with a germline PTEN mutation: a combination of extremely rare diseases with probable further implications.

BMC Med Genet 2018 08 15;19(1):144. Epub 2018 Aug 15.

Institute of Medical Genetics and Applied Genomics, University of Tübingen, Calwerstr. 7, 72076, Tübingen, Germany.

Background: The PTEN-hamartoma-tumor-syndrome (PHTS) is caused by germline mutations in Phosphatase and Tensin homolog (PTEN) and predisposes to the development of several typical malignancies. Whereas PTEN mutations have been implicated in the occurrence of malignant mesotheliomas, the genetic landscape of verrucous carcinomas (VC) is largely uncharted. Both VC and malignant peritoneal mesotheliomas (MPM) are exceedingly rare and a potential link between these malignancies and PHTS has never been reported. Read More

Tuberous sclerosis complex.

Handb Clin Neurol 2018 ;148:813-822

Department of Neurology, University of Maryland School of Medicine, Baltimore, MD, United States. Electronic address:

Tuberous sclerosis complex (TSC) is an autosomal-dominant or sporadic multisystem disorder that results from mutations in either TSC1 or TSC2. The primary organs affected include the brain, skin, lung, kidney, and heart, all with variable frequency, penetrance, and severity. There are over 2000 known allelic variants for TSC, including nonsense and misssense mutation, and all pathogenic mutations are inactivating, leading to loss-of-function effects on the encoded proteins, TSC1 and TSC2.

and Associated Conditions: Identification of At-risk Individuals and Recommended Surveillance Strategies.

Clin Cancer Res 2018 May 17;24(10):2251-2261. Epub 2018 Jan 17.

Department of Pathology, Center for Cancer and Immunology Research, Children's National Medical Center, Washington D.C.

Pathogenic germline variants cause a hereditary cancer predisposition syndrome with a variety of manifestations. In addition to conferring increased cancer risks for pleuropulmonary blastoma (PPB) and ovarian sex cord-stromal tumors, particularly Sertoli-Leydig cell tumor, individuals with pathogenic germline variants may also develop lung cysts, cystic nephroma, renal sarcoma and Wilms tumor, nodular hyperplasia of the thyroid, nasal chondromesenchymal hamartoma, ciliary body medulloepithelioma, genitourinary embryonal rhabdomyosarcoma, and brain tumors including pineoblastoma and pituitary blastoma. In May 2016, the International PPB Registry convened the inaugural International Symposium to develop consensus testing and surveillance and treatment recommendations. Read More

Endobronchial hamartoma mimicking malignant lung tumor contralateral endobronchial metastasis: A case report.

Medicine (Baltimore) 2017 Dec;96(49):e9085

aDepartment of Respiratory and Critical Care Medicine, Jiangxi Provincial People's HospitalbDepartment of Cardiology, the Second Affiliated Hospital of Nanchang UniversitycDepartment of Pathology, Jiangxi Provincial People's Hospital, Nanchang, China.

Rationale: Endobronchial hamartoma, the most common benign lung tumor, is located in the bronchus, and it easily mimics lung cancer or bronchial metastasis. Endobronchial hamartoma can cause coughing, hemoptysis, and pulmonary infection; thus, it should be treated right away by surgery or fiberoptic bronchoscopy.

Patient Concerns: We report a rare case of endobronchial hamartoma in which the clinical symptoms and imaging overlapped strongly with malignant lung tumor contralateral endobronchial metastasis. Read More

Successful use of snare electrocautery via flexible fiberoptic bronchoscopy for removal of an endobronchial hamartoma causing chronic lung atelectasis and mimicking malignancy.

Ther Adv Respir Dis 2017 12;11(12):435-438

Respiratory Department, The First Affiliated Hospital of Soochow University, 188 Shizi Street, Suzhou, 215006, China.

We present a rare case of giant endobronchial hamartoma coexisting with lung atelectasis for more than 3 years. The small specimen initially biopsied via bronchoscope did not reveal tissue features, but some features were suspicious for squamous cell carcinoma. The lesion was removed completely using snare electrocautery combined with argon plasma coagulation via flexible fiberoptic bronchoscopy. Read More

Notch transactivates Rheb to maintain the multipotency of TSC-null cells.

Nat Commun 2017 11 29;8(1):1848. Epub 2017 Nov 29.

Department of Immunotherapeutics and Biotechnology, School of Pharmacy, Texas Tech University Health Science Center, 1718 Pine Street, Abilene, TX, 79601, USA.

Differentiation abnormalities are a hallmark of tuberous sclerosis complex (TSC) manifestations; however, the genesis of these abnormalities remains unclear. Here we report on mechanisms controlling the multi-lineage, early neuronal progenitor and neural stem-like cell characteristics of lymphangioleiomyomatosis (LAM) and angiomyolipoma cells. These mechanisms include the activation of a previously unreported Rheb-Notch-Rheb regulatory loop, in which the cyclic binding of Notch1 to the Notch-responsive elements (NREs) on the Rheb promoter is a key event.

Cystic Lung Disease in Genetic Syndromes with Deficient Tumor Suppressor Gene Function.

Respiration 2017 23;94(6):467-485. Epub 2017 Nov 23.

Cystic lung diseases constitute a distinct group of rare lung disorders, among which two result from monogenic defects affecting tumor suppressor genes: lymphangioleiomyomatosis, either sporadic or associated with tuberous sclerosis complex, and Birt-Hogg-Dubé syndrome. These disorders have similarities in their clinical expression, including occurrence in young adults, multiple pulmonary cysts, recurrent pneumothorax, skin hamartomas, and renal tumors. However, they markedly differ in their gender distribution, pathogenesis, disease course, and prognosis. Read More

A three-microRNA signature for lung squamous cell carcinoma diagnosis in Chinese male patients.

Oncotarget 2017 Oct 28;8(49):86897-86907. Epub 2017 Jul 28.

Department of Oncology, First Affiliated Hospital of Nanjing Medical University, Nanjing 210029, PR China.

Various studies have demonstrated the diagnostic value of microRNA (miRNA) for lung cancer, but miRNA signatures varied between different subtypes. Whether serum miRNAs could be used as biomarkers in lung squamous cell carcinoma (SCC) remains unknown. Using quantitative real-time polymerase chain reaction (qRT-PCR) based Exiqon panel, 38 differentially expressed miRNAs were identified from 3 male lung SCC pool samples and 1 normal control (NC) pool in the initial screening phase.
